Hi All, Thanx for loads of information on Daughter Card (PCM3003). I have gone through the code given in Dr. Rulph Chassaing's book(implemented by W.J. Gomes III). But I have not been able to understand How this has been implemented using only one McBSP? I have a confusion with regard to the LEFT and RIGHT channels of the codec. Are these 2 channels(left/right) physically seperated on the board? If yes, then how one can access them using only one serial port? I don't know whether I have framed the question in a right way?...!!! Can somebody throw light on this? Thanks in advance.... Regds Anand |

I think you asked your question correctly - however - it's obvious that you didn't read the datasheet of that codec ;-) well - good luck man - if you have any further questions - feel free to ask... __________________________________ |
